In order to find the best replacement bearings and seals for your Harbor freight Trailer, you will need to remove the wheel and hub and pull the bearings, seals, and races off your spindle. I have attached a photo that shows where you can find the numbers on those items. We don't offer bearings in mm sizes but you might still be able to find what you need.

If you are not able to find the numbers on these items, you will need to take some measurements of the spindle with a precision instrument like a digital caliper in the locations as shown in the attached photo.

Typically, Harbor Freight uses non-standard size bearings and it may be difficult to find any that would work for you. If you wish to give the dimensions, we can make a recommendation for a replacement axle that would work on your trailer.

I have also included a helpful article that shows how to replace the bearings, races and seals you can check out.
